Hi Jaza,
I have the same problem too. You cant see the waves inside of Ports.
Some Steam Users have this problem and vstep knows it since a long time (3/4 Year).
There is a solution for this problem, found out by our forum member Thor but vstep must do it.
So we just can wait and hope they will bring us the solution with the next patch or a soon hotfix.
Happy New Year
